Textbook in PDF format Materials Chemistry, a broad dscipline including hard and lightweight materials, bio-materials and superconductors, as well as the more traditional materials such as ceramics, polymers, and glasses focusing on the structure-property paradigm. Each class of materials highlights recycling techniques, and green methods of production. This book includes subjects on: defect structure, crystal structure, semi-crystalline materials, semi-conductors, superconductors, polymers, metals and alloys, bio-materials, ceramics, glass, lightweight materials and hard materials. An emphasis is placed on emerging subjects and discoveries throughout the field, as well as the possibilities of recycling of materials. The author examines all the relevant and newly emerging sub-disciplines within materials chemistry, without minimizing the already well-established subjects within the field. Materials Chemistry provides a broad survey of this field for those being first exposed to materials chemistry. It is useful to advanced students, as well as to professionals in the field. Covers the materials chemistry field in a wide range. Highlights the new, cutting-edge developments that fall within materials chemistry. Examines all materials in the context of what is called a circular economy.
